In 2013, as a response to rising inequalities, poverty and distrust in the EU, the Commission launched a major endeavour to rebalance economic and social policies with the Social Investment Package (SIP). Funded under the Horizon 2020 Programme, the RE-InVEST project aims to strengthen the philosophical, institutional and empirical underpinnings of the SIP, based on social investment in human rights and capabilities. The project will actively involve European citizens severely affected by the crisis in the co-construction of a more powerful and effective social investment agenda.
